Subject: Factor Theorem Name: Yael Who is asking: Student Level: Secondary Question: Hi, I'm not sure what to do with this question:
Prove (x - a - b) is a factor of
x I don't know even how to start it! Thanks Hi Yael,
The integer 3 is a factor of 414. I know this because, if I divide 414 by 3 the remainder is zero. You could apply the same argument here. Divide x The factor theorem states that ^{3} - a^{3} - b^{3} - 3ab (a + b)
f(a + b) = (a + b)
Expand (a + b) To return to the previous page use your browser's back button. |
